Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54720, here are decompositions:
- 7 + 54713 = 54720
- 11 + 54709 = 54720
- 41 + 54679 = 54720
- 47 + 54673 = 54720
- 53 + 54667 = 54720
- 73 + 54647 = 54720
- 89 + 54631 = 54720
- 97 + 54623 = 54720
Showing the first eight; more decompositions exist.
